I have one plant that is very spindly and pale yellowish compare to the others. I switched brands of liquid fertilizers this time but, other than my screw-ups, most are doing reasonably well, considering I tend to kill everything that's green.

After following directions from the nutrient maker, a well-respected high-end brand who shall remain nameless, nothing improved. So out of desperation I decided to go foliarly chemical on that one plant.

I bought a cheap generic version of Miracle Grow soluble high nitrogen granules (24/8/16), mixed it a bit weak, moved the plant out of direct sunlight into bright open shade, and sprayed it liberally. After it dried I moved it back into bright direct sunlight. After a few hours it already looked a tiny bit better. I'll spray it again in the morning before putting it in direct sunlight.

I thought I'd done something goofy with soil or nutrient PH but since this seems to be working I'm wondering if this plant dislikes this brand of nutrients.

I'm wondering if some plants are nutrient hogs? I have earlier started a bunch of clones for outdoors and 1 clone is pale green with a couple leaves trying to turn yellow. The same variety right next to it is a darker green with no pale leaves. I have foliar fed it so I am waiting to see what happens.

Should I spray every day or wait a few days between sprays?

I don't know enough to answer your question. But I'm spraying twice daily to see what happens.

Pretty sure your on track w this post.
Question is...
Which nute or nutes is that particular plant hogging.

Would be interesting to know which deficiency we're talking about... or if it's even a deficiency. Had some plants myself which were light green by nature. Have any pictures?

If it's nitrogen, then spraying ~0.5% urea would be the solution but only if you're growing in soil (-> urease enzymes require trace amounts of nickel which isn't necessarily present in soilless media or water cultures).
Fairly good foliar sulphur sources would be ammonium sulphate or thiosulphate. Though the latter is allegedly better/faster assimilated it might have some drawbacks you don't want to challenge. If ammonia isn't wanted, go with potassium sulphate or apply Epsom salt best as foliar spray and soil drench.
Other deficiencies causing brighter green colours could be magnesium (see also sulphur), iron, manganese, and zinc. These are usually applied either in chelate form (e.g. as bisglycinate) or as sulphate salt. Most of these deficiencies shouldn't be just remedied by foliar application but also as soil drench to eliminate it in the whole plant and not just the spots where the spray droplets hit the leaves (-> +/- immobile micronutrients or too high demands to be cured by spray alone regarding secondary nutrients).

I was thinking it might just be the phenotype but after spraying with the high nitrogen nutes it's a tiny bit greener overall and has some darker green areas around the veins. I'll post pics in a few minutes. When you see the pics, please don't make fun of my poor sickly little plant.

You know, I'm about to make fun.. not of your plants (which I haven't seen yet) but of you cause it takes you bout an hour to post a single pic . Or maybe you're bakes... prolly I should do that too, just for a change.
